Information about Silfra


Earth is divided with underground tectonic plates. Iceland is situated right in the middle of the two of them – North American and Eurasian Tectonic Plates. Silfra Fissure is one of the places in Iceland where you can see where the tectonic plates have slowly been separating – yet not on land, but under water. 

In this magical place, the water is considered to be one of the cleanest waters in the world, with a visibility of more than 100 meters. This incredibly clean water comes from the melted ice of Langjökull glacier.

Join us on an adventure in Silfra – the only place in the world where you can snorkel in the middle of two tectonic plates.

Tour Description


You will need a car to join this activity. Silfra Fissure is located in the Thingvellir National Park – around 50 minutes away from Reykjavik. If you do not have a car, you can add an option to get a transfer from Reykjavik and back (for an additional cost). 

Once you get to the location, it is important to give your snorkeling guide a filled medical form (it is important to read the medical form before booking the tour). Your guide will then give you all the equipment – a thermal undersuit to keep you warm, a dry suit to keep you dry, fins to swim, and other necessary snorkeling equipment.

Once you get warm and ready, your guide will teach you how to snorkel, what to do if you get tired in the water, and other important information.

You can leave all your clothes and other items in our Tröll bans, which are kept securely at all times. You will then start walking towards Silfra with your dry suit on. The walk to Silfra is short, roughly 5 minutes long.

Once you get to the location, just jump into the crystal clear water, and enjoy one of the most beautiful places on earth! 

During the activity, you will be swimming between two tectonic plates. Your guide will eventually send you all the GoPro photos after the tour.


Is Snorkeling in Silfra Difficult

Snorkeling in Silfra is very easy – there is no need to have a lot of power. During the first part of the tour, a current from melting glacier water will be slowly pushing you, so you can just relax and enjoy the magical underwater life. 

It is however important not to be afraid of water, and have basic knowledge of swimming.


Will I feel cold while snorkeling in Silfra

Most people do not feel cold during the snorkeling part as the dry suits keep you warm. It might however get a bit colder during winter time after you get out of the water – the air temperature in winter is usually colder than the water itself.


Does the water in Silfra freeze in winter

No, because new melted glacier water enters Silfra each day, so the water never gets the time to freeze. Water in Silfra remains between 2°C and 4°C all year round.


Why is the water in Silfra so clean

Once the ice from a glacier melts, the glacier water gets filtered through underground lava on its way down to Silfra. The pores from the lava eventually end up cleaning the water, which eventually allows us to explore the magical, mysterious life between the tectonic plates.
